BERSIGAR Ocular 1766: Vintage Black Steel Edition
The BERSIGAR Ocular 1766 Vintage Black Steel Edition fuses mid-century motorsport track heritage with modern, ultra-slender case architecture. Defined by a balanced 40mm stainless steel case engineered with an 11mm slim profile, a fixed circular-brushed steel tachymeter bezel, a textured matte black dial with warm patinated indices, broad-arrow hands, and a solid three-link stainless steel bracelet, this meca-quartz chronograph delivers authentic vintage tool-watch appeal with daily durability.
Powered by the Seiko Japanese TMI VK64 meca-quartz movement, the hybrid caliber unites the timing precision of quartz with a mechanical chronograph mechanism that offers crisp tactile pusher engagement and an instantaneous zero-reset flyback hand. The matte black dial features warm vintage-toned luminous baton markers, an arrow index at 12 o'clock, faceted broad-arrow hands, and two sunken sub-registers tracking 60-minute elapsed timing and a 24-hour cycle. Built from solid 316L brushed and polished stainless steel, the watch is equipped with an anti-reflective sapphire crystal, classic pump pushers, a threaded screw-down crown, and 10 BAR (100M) water resistance.

From the journal
Owners say
I was skeptical buying a $220 chronograph online, but the solid 316L steel bracelet and sapphire crystal feel like watches twice the price. Also threw it on a spare leather strap for a few days, though that leather was stiff for the first 3-4 days.
Thanks for giving us a try, Alexander! Happy to hear the steel bracelet and sapphire crystal impressed you.
Bought this for my son's 40th birthday. He was thrilled with the vintage black dial and solid feel. Only heads up is bracelet resizing took 15-20 minutes because a couple of the split pins were pretty stubborn.
As someone who collects vintage-inspired chronographs, the 40mm Ocular 1766 hits a great proportion for my wrist. The Seiko VK64 meca-quartz caliber drops the running seconds hand, which lets the matte black dial and patinated markers look like a classic hand-wound two-register piece until you engage the 5Hz sweep. Solid 316L end links, clean brushing on the fixed tachymeter bezel, and an anti-reflective sapphire crystal round out a very smart package.
Took this out for a weekend autocross event. The VK64 pushers have a firm click, the bi-compax sub-registers are easy to read at a glance, and the fixed steel tachymeter bezel looks classic on my wrist.
I prefer menswear-style chronographs over tiny ladies watches, and at 40mm this fits my wrist really well after removing four links. The matte black dial and steel bracelet pair easily with blazers at the office.
Retired Navy here, and I have always liked classic 1960s issue chronographs. The 40mm case, fixed brushed tachymeter bezel, and Seiko VK64 meca-quartz pushers give you that crisp mechanical stopwatch snap without the maintenance headache.
Wore this to the shop and out to dinner all week. The matte black dial with the warm vintage markers looks even better in sunlight than on the site, and the 40mm steel bracelet is super comfortable.
Thanks Steve! Glad that vintage black dial is getting plenty of wrist time.
